so does that make it a liquid? Sand can be poured, so does that make it a liquid?

Discuss the different materials in front of you. Would you class them as a solid or a liquid?

Now you’re an expert, make a 2 minute film to explain solids and liquids to others using the resources on your table as evidence.
